Definitions

  • the present invention relates to disconnecting or insulating switches, and more particularly to disconnecting switches for high voltage installations.
  • the present invention is intended in the first 1 line for open air installations.
  • the present invention is not limited to disconnecting switches for Open air installations but can also be used for i'nstallationslocated indoors.
  • a disconnecting switch according to the present invention consists in a disconnecting switch for high voltage installations, comprising in combination, a pair of movable arms, contact pieces arranged on the arms, respectively, the contact pieces being arranged with respect to each other for engagement at a predetermined relative position of the movable arms, the contact pieces being rotatable about the axes of the arms,
  • the movable arms are hollow and the resilient means are arranged inside the arms and connected to the contact pieces so as to 'oppose the rotation of the contact pieces after engagement thereof.
